The part number **JH24240320ECNUWNTHCWC** refers to a high-resolution, small-form-factor **Liquid Crystal Display (LCD)** module, typically used in industrial or smart wearable applications. Below is a breakdown of the electronic specifications and features associated with this component. --- ### 1. General Specifications This display is characterized by its square aspect ratio and high pixel density. | Feature | Specification | | :--- | :--- | | **Display Type** | TFT LCD (Thin Film Transistor) | | **Resolution** | 240 x 240 Pixels | | **Size** | Approximately 1.3 to 1.5 inches (Diagonal) | | **Interface** | SPI (Serial Peripheral Interface) or MCU 8-bit | | **Color Depth** | 65K / 262K Colors (16-bit / 18-bit) | | **Touch Panel** | Capacitive Touch (indicated by "TC" in suffix) | --- ### 2. Pinout & Connectivity The module typically uses a **Flexible Printed Circuit (FPC)** connector. While specific pin maps vary by revision, the standard logic for these displays includes: * **VCC/VDD:** Power supply for the logic (usually 2.8V - 3.3V). * **LEDA/LEDK:** Backlight Anode and Cathode pins. * **SCL/SDA:** Clock and Data lines for SPI communication. * **RES/RST:** Hardware Reset pin. * **DC/RS:** Data/Command selection pin. * **CS:** Chip Select. --- ### 3. Key Electronic Components The functionality of this module relies on three main sub-systems: #### A. The Display Driver IC (DDIC) The "brain" of the module is usually an integrated circuit like the **ST7789V** or **GC9A01**. It handles the GRAM (Graphic RAM) and converts digital signals into analog voltages to drive the liquid crystals. #### B. The Backlight Circuit It consists of a series or parallel array of White LEDs. ```markdown Typical Operating Current: 15mA - 20mA Typical Forward Voltage: 3.0V - 3.2V ``` #### C. Capacitive Touch Controller The "TCW" portion of the part number suggests a **Capacitive Touch** interface, likely driven by an I2C controller (such as the **CST816S** or **FT6336**), allowing for multi-touch gestures. --- ### 4.
